Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, specifically to a cardboard box surface printing device. Background Technology

[0002] A cardboard box surface ink printing device refers to a mechanical device specifically used for printing patterns, text, or other information on the surface of cardboard boxes. Common cardboard box surface ink printing devices include screen printing machines. The working principle of a screen printing machine is based on screen printing technology. Its specific components include: a screen, a screen stretching machine, a squeegee, a worktable, positioning blocks, and an ink system. The screen consists of a screen and a frame, coated with photosensitive emulsion and with through-holes for the graphic elements. The squeegee applies pressure to the screen, causing the ink to transfer through the openings to the cardboard box surface.

[0003] Currently, the existing cardboard box printing equipment for cardboard box processing is inconvenient to load, and paper scraps and dust inevitably remain on the surface of the cardboard box during production. If the paper scraps and dust are not cleaned, the printing quality will be affected, resulting in certain shortcomings. Therefore, we propose a cardboard box surface printing device for cardboard box processing. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a cardboard box surface printing device for cardboard box processing, including a mounting base 1, a conveyor belt 2 arranged inside the mounting base 1, side plates 3 fixedly installed on both sides of the mounting base 1, a printing device body 4 fixedly installed inside the side plates 3, a first mounting plate 5 fixedly installed inside the side plates 3, a horizontal cylinder 6 fixedly installed on the top of the first mounting plate 5, a vertical cylinder 7 fixedly installed at the output end of the horizontal cylinder 6, a first mounting frame 8 fixedly installed at the output end of the vertical cylinder 7, a negative pressure pump 9 installed on the top of the first mounting frame 8, a plurality of suction cups 10 arranged at the bottom of the first mounting frame 8, the working end of the negative pressure pump 9 connected to the working end of the suction cups 10, and a second mounting plate 11 fixedly installed on one side of the side plates 3. A blower 12 is installed at the top, and an air distribution plate 13 is fixedly installed at the output end of the blower 12. Several printing device bodies 4 are set at the bottom of the air distribution plate 13. A material lifting mechanism is set at the bottom of one side of the mounting base 1. A control box is set below the mounting base 1. A limit belt 27 is set on the inner side of the side plate 3. The limit belt 27 cooperates with the conveyor belt 2. A power source for driving the conveyor belt 2 is set on one side of the mounting base 1 (the power source can be a motor, which drives the transmission roller to rotate and thus drives the conveyor belt 2 to run). A power source for driving the two limit belts 27 is set on one side of the side plate 3 (the power source can be a motor, which drives the transmission roller to rotate and thus drives the limit belts 27 to run). This printing device is only suitable for folded and unfurled cartons. It is not suitable for unfolded cartons.

[0021] The lifting mechanism includes a lifting box 15, which has an installation cavity 16 inside. A lead screw 17 is rotatably mounted inside the installation cavity 16 via bearings. A worm gear 18 is fixedly mounted on the outer side of the top of the lead screw 17. A servo motor 19 is fixedly mounted inside the installation cavity 16. A worm gear 20 is fixedly mounted on the output end of the servo motor 19. The worm gear 20 meshes with the worm gear 18. A sleeve block 26 is mounted on the surface of the lead screw 17. The sleeve block 26 and the lead screw 17 cooperate to form a lead screw slider drive structure. A loading seat 21 is fixedly mounted on one side of the sleeve block 26. A guide rod 25 is fixedly mounted inside the installation cavity 16 and on one side of the lead screw 17. The sleeve block 26 and the guide rod 25 are slidably connected. The function of the guide rod 25 is to limit and guide the sleeve block 26.

[0022] A second mounting bracket 22 is installed on the inner side of the side panel 3. A fan 23 is provided at the bottom of the second mounting bracket 22. An electric heating wire 24 is installed on the inner side of the second mounting bracket 22 and above the fan 23. The function of the second mounting bracket 22, the fan 23 and the electric heating wire 24 is to quickly dry the ink after printing on the outside of the carton, thereby avoiding the situation where the ink cannot dry quickly after printing and the printed area is wiped off due to friction.

[0023] The printing unit body 4 is a Linglong direct output G4P-1624 printing press.

[0024] In summary, the cardboard box surface printing device for this cardboard box processing operates as follows: An unopened cardboard box is placed on the loading seat 21, and printing begins. The control box activates the servo motor 19, driving the worm gear 20 to rotate. The worm gear 20 meshes with the worm wheel 18, driving the lead screw 17 to rotate, which in turn moves the sleeve block 26 upwards via the thread, thus raising the cardboard box to one side of the conveyor belt 2. The control box then activates the blower 12, which blows air into the air distribution plate 13 and then sprays air onto the cardboard box through the nozzle 14, cleaning the cardboard box surface. The control box then controls the horizontal cylinder 6 to push the vertical cylinder 7 to move laterally, causing the suction cup 10 to move above the cardboard box. Finally, the control box activates the vertical cylinder 7 and the negative pressure pump 9, which... After cylinder 7 is activated, it pushes suction cup 10 down to contact the top of the cleaned and dust-free cardboard box. Then, negative pressure pump 9 is activated, causing suction cup 10 to hold the cardboard box under negative pressure. Then, the control box controls horizontal cylinder 6 and vertical cylinder 7 to reset, causing suction cup 10 to move the adsorbed cardboard box above conveyor belt 2. Then, the control box controls negative pressure pump 9 to turn off, allowing the cardboard box to fall onto conveyor belt 2. Finally, the control box controls conveyor belt 2 and limit belt 27 to open, transporting the cardboard box to the printing end below the printing device body 4 for printing. After printing, the cardboard box is transported to below fan 23. Finally, the control box turns on fan 23 and energizes heating wire 24, so that hot air is blown onto the cardboard box by fan 23 to dry the ink quickly, thus completing the printing.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
